Abstract

PURPOSE: To obtain a novel polyester-amide having improved mechanical strength, impact resistance, transparency, softness, oil resistance, water resistance, adhesive property, flexibility, etc., by copolymerizing ester units with amide units each having a specific structure in a specific proportion.
CONSTITUTION: A polyester having an average polymerization degree of 3W8 and ester units expressed by formula I and/or II is copolymerized with a nylon salt consisting of formula III (m is an integer 6W12) anf formula IV (n is an integer 6W10) or an aromatic dicarboxylic acid under vacuum at 200W270°C to give the aimed polyester-amide having (A) the ester units expressed by formula I and/or II and (B) amide units expressed by formula V (R is formula VI or monocyclic aromatic nucleus) at a weight ratio between the units (A) and (B) of 20:80W95:/5.
USE: Useful for a molded article, e.g. a fiber or film, a hot-melt adhesive for metal, fiber, plastic or wood, a solution adhesive, a coating material, etc.
